±400 kV青藏直流联网工程换流站三维数字化移交推进了三维设计技术在换流站设计中的应用。工程选取通用的三维设计平台，同时兼顾业主管理的方便性，力求通过通用的操作界面实现专业化的移交内容。在换流站工程移交运行单位的同时，提供了格尔木换流站和拉萨换流站1∶1的真实三维模型及分类整理的施工图电子文档，以利于业主管理和运行维护。

The three-dimensional digitalization transfer of Qinghai-Tibet ± 400 kV DC interconnection project aims to promote the application of three-dimensional design technology in the converter stations design. The project made effort to realize professional transfer information with universal platforms by adopted universal three-dimensional design software and considering the convenience of owner management. When Lhasa and Golmud stations were transferred to the operation company, the real three-dimensional models and the classified construction drawings of stations were provided, which was beneficial to these two stations owner management and operation maintenance.
